Application March 14, 1936, Serial No. 68,859 i 1 Claim. (Cl. 5-264) .i

My invention relates to bed springs,- and has reference moreparticularly to the novel means of attaching the cross bars to the mainframe.

In the attached drawing forming part of this s application, Figure` 1 isa fragmentary top plan of a spring embodying my invention.

Figure 2 is a fragmentary 'plan of the bottom of the spring unit, onlythe bottom frame being shown and the bars attached thereto;. other partsbeing shown in dotted Alines or entirely eliminated to better show theinvention, and

Figure 3 is a vertical section on line 3-3, Fligure 1.

Referring to the drawing', 5 is the main frame in the shape of arectangle, preferably made of ang1eiron,'which at suitable intervals onits longer sides is provided with lugs 6 secured rigidly Y to the frame.Running transversely of the length of the frame 5 are cross bars 1,spaced so that the attened ends 3 of said bars will lie intermediate ofthe lugs 3.

To each attened end 8 of the bar 1 is secured a yoke 3. The proximateends of the yokes 9 and the lugs 6 are interconnected by tension springsID, all of said-springs normally lying in a plane parallel to the mainframe 5 and acting atl substantially right angles to the bars 1. Thebars 1, adjacent to the ends of the frame 5, have their yokes 3connected to the frame di- 80 rectly by springs I0.

A secondary frame I3, also of a rectangular shape and made of angleiron, is. positioned above the main frame '5 where it is supported bycompression coil springs IIv and I2 carried by the cross bars 1. Atthevery ends of the cross bars,

. '.only springs II are provided for the said cross bars are bent at theends, as bestI shown in Figure 3. In other words, at the extremities ofthe cross bars 1, there is no room for springs I2,

4o so that at the longer side of the frame 5 compression springs IIronly are used.

Running intermediate of the springs II (see Figure 1), are strips I4running transversely of the secondary'frame i3, and strips I5 runninglongitudinally of said frame. In said Figure 1,

only one coil spring II is fully -shown in the corner; all the othersprings are indicated by the upper loop of the coil spring so as tobetter illustrate the invention.

PATENT oFFl-CE f The overlapping parts o f the strips I4 and I5 areunited by clips Il which serve also as an-v chors for tension springsI1, which unite the proximate top loops of coil springs I2 -to saidclips. Each end of the strips I4 and I5 are connected to the vsecondaryframe I3 by a tension spring I8.

Any pressure applied to the strips, and in con# sequence, to thesecondary frame I3, is transposed by the coil'springs II and I2 to thecross frame intermediate of the bars, yokes provided on the end of thebars, tension springs lying in a plane substantially parallel to theframe and yokes, and running substantially parallel to the sides of theframe connecting the ends of the yokes to proximate lugs, a secondaryframe, and

cushion springsl interposed between and opera'- tively connected to thesecondary frame and the bars. n
